We use a Chase Bank joint account, but Schwab looks pretty legit. We only have one account, and neither of us wanted it differently.
We were honest about our debt and assets while dating. We saw each other's FICO scores for all 3 bureaus while engaged. We then decided on financial goals and what we wanted out of life prior to marriage. We set a budget for retirement, investments, savings, bills, etc.
With direct deposit, online bill pay, mobile banking, etc. there really isn't much of a reason to go to a branch except maybe applying for a home loan.
We have a text sent to our phones if anything over $10 is deposited, withdrawn, or transferred from our checking or savings accounts in case of fraud. I don't bug her about what she buys, and she doesn't bug me. If we spend more than $100 for non-essentials then we discuss it with each other prior. However, we've found that when we're responsible with our money we don't care if the other person splurges on something.
I hope I never feel like she holds my jewels in her purse, or she feels like I'm her father. We don't always agree, but we find we can always come to a common understanding when we work towards a solution together.
